To ALL WHoM I'r MAY CONCERN:

Be it known that I, AMOS HADLEY, of Washington, in thecounty of Washington, and District of Columbia, have inventeda new and useful Improvement in Business-Registers or Door-Plates; and I do hereby declare that the following is a. full, clear, and exact description thereof, reference being had to the accompanying drawings, and the letters of reference marked'thereon, in which- Figure 1 is a front view.

Figure 2 is a front view of the plate cl and `wheel g.

The nature of my invention consists in providing a neat and convenient method whereby any business man, when supplied with this article, can, by placing it over his deskl or upon the outside of his voffice-door,readily .set it to indicate his whereabouts, orthe time at which he will return, thus affording the information desired by callers,'thereby preventingtheir waiting, when the person desired will not return for some time, or preventing the going away of callers because the proprietor is out; a moment, and has left no indication of the time he is-to bc absent. Also, making a neat and attractive business-card for an oce or chico-door.

Its construction and operation are as follows: The front, a, is made of thin metal or card-board, and of any desired size or form. It may have an ornamental frame or border around it, as seen at b Zgg. 1.- On one side of the ccntrc of the front piece a, I make an orifice, c, which is covered with mica to prevent the indieatoi` from being tampered with. Over the orifice is placed the name of the proprietor, and upon other parts of the front, a, his business-card, office-hours, residenee,'&c. Back ot'and against thefront piece a is placed a thin frame, d, and next to that a thin-piece ot' wood, the same size of the front piece, this forming the back, thus leaving a. thin or shallow space between the front and back, which is surrounded by the frame 02. 'lhe front, ft, frame d, and' back are securely fastened together. In this space is placed a wheel, g, made of' thin metal or card-board, which is revolved by a spindle,f, whose bearings are the front piece a and the back. The form of the wheel is shown in fig. 2. On the side of the rim, and una line drawn from the centre of'thc wheel, are printed the numbers indicating the hours ofthe day ornight, the days ofthe week, and soon or upon which may be printed any other Iigures or words necessary to adapt the register more particularly to the convenience of any individual, er to any other uses. The rim ofthe wheel g is connected to the hub by bars or spokes, t i, as lseen in fig. 2. These bars are of about the' same width alsthe oriiicec of the front, a, and upon' the face of the said bars arc printed the phrases, Is ont, Is in, Is at dinner," arid Is out of town, onev phrase being upon each bar; or anything else may be placed upon them that would add to the convenience of the individual, or to otheruses.

Opposite the orifice c, on the back, is printed the phrase, Will he in at, (or any other desirable one,) which phrase shows'throngh the oriiicc c, between the bars V7i of the wheel (j, except when the bars L shallintervene between it and the orifice c, and exhibit one of the phrases thereon. The phrase 'Will be in at, when showing through the orice c, unites with the figures on the rim of the wheel g, thus indicating any hour or day, or when the proprietor will return, if out, or away from his place of business.

Used as a register door-plate, fastened on thc outside of a door, the spindlefpasses through the door to the inside ofthe oice, thus preventing it from being tampered with'from thc'outs'ide, but for use inside an ollce or for a front hall, the knob is on the face of the register.

Having thus fully described my invention, what I claim, and 'desire to secure byLctters Patent,

The rotating disk between the two Stationary plates, all as shown and described, and for thc Apurposes specicd.'

AMOS HADLEY. Witnesses:
